bcm53xx: add support for the PCIe controller 

This patch adds support for the PCIe controller
In addition to the PCIe controller a sprom is now provided by a device
tree driver to bcma from some nvram.

Subject: [PATCH 02/15] bcm47xx: move the nvram header file into common space
Moving mach-bcm47xx/bcm47xx_nvram.h makes it possible to reuse this
header on the arm bcm47xx (BCM5301X) devices. This way a driver gets
the correct functions to access the nvram depending on the SoC it boots
for.

Subject: [PATCH 03/15] bcm47xx-nvram: add new nvram driver with dt support
This adds a new nvrm driver which uses device tree to provide nvram
access to other drivers. You have to specify the memory ranges where
the flash chip is mapped and this driver will search there for some
nvram and parse it. Other drivers can use this driver to access the
device nvram. The nvram is used to store board configurations like the
mac address and also for configuration values in the vendor firmware.

Subject: [PATCH 04/15] bcm53xx-sprom: add sprom driver
This driver needs an nvram driver and fetches the sprom values from the
sprom and provides it to any other driver. The calibration data for the
wifi chip the mac address and some more board description data is
stores in the sprom.

Subject: [PATCH 13/15] pci: do not probe too early
Probing is done before the PCIe bridge is fully activated and the
address spaces does not get assigned to the PCIe devices. Without the
address space the driver can not register to this device. With this
patch the driver reregistration is done later.

These are some hackish patches to make the Ethernet driver work somehow
on this arm core.
The flash driver is not working, so we removed the nvram reading, this
should be changed after we have a flash driver.
The mdelay(1) is a ugly workaround for this arm chip, this seams to be a dma problem.
The PHY says it is not connected by default, just ignore it.
